- ONTAP 9
- Clustered Data ONTAP
- Linux kernel 2.6.18 and later versions
- Modern Linux clients identifies the
.snapshotdirectory as a different filesystem, and thus as a different mount point.
- When the snapshot is deleted, clients report 'stale file handle' for .snapshot based sub-mounts
- 'mount' command on the Linux host displays a large number of snapshots mounted and not able to be unmounted.
